White double connector with (I believe) brown and blue wires. Use a dwell
meter on 8 cyl scale. Convert to duty cycle by multiplying duty cycle by .9
= dwell. Divide x 2 for 4 cyl scale.
Under open loop conditions the duty cycle will be a set, non varying value.
The higher the value, the richer (as I recall). I'll CC: this to the list so
I can be corrected...
Closed loop will cycle back and forth about 8-10 degrees max. Put long wires
on it, put in seat next to you - take it for a drive from cold and you
should see it go from open to closed loop as it warms up. When you hit WOT
it'll go open loop again.
